Blocked gene may provide new treatment for allergies
Allergic reactions like hay fever can recur over long periods since the allergenic mast cells survive and revive. A team of Uppsala scientists have now identified the mast cell's survival gene, and by blocking this gene, they can inhibit allergic reactions, opening new avenues for treatment. These findings have been published in Monday's issue... view more... (2001-12-05)
New cheaper method for mapping disease genes
Scientists at the Swedish medical university Karolinska Institutet have developed a new DNA-sequencing method that is much cheaper than those currently in use in laboratories. They hope that this new method will make it possible to map disease genes in large patient groups, which in turn can mean quicker breakthroughs for new treatments for a wide... view more...

Eavesdropping comes naturally to young song sparrows
Long before the National Security Agency began eavesdropping on the phone calls of Americans, young song sparrows were listening to and learning the tunes sung by their neighbors. view more (2007-05-31)
Scientists puzzled by severe allergic reaction to cancer drug in the middle Southern US
A patient's expectations about the side effects of chemotherapy usually focus on nausea, hair loss, fatigue and other side effects. Worries about severe allergic reactions to their therapy is usually not a concern. view more (2007-08-21)
Slowing the racing heart
Researchers at the University of Illinois at Chicago explain in the May 11 issue of Circulation Research how an enzyme acts on the heart's pacemaker to slow the rapid beating of the heart's "fight-or-flight" reaction to adrenaline. view more (2007-05-14)
Discovery of new biological principle can give better cancer treatment
Pioneering research on leukaemia cells can have identified their vulnerable spot. This new knowledge can now be used to produce more effective medicines. view more (2004-09-13)
Sick Beans lead to Nanotech
Farmers get little joy from the cowpea mosaic virus, which attacks legumes. Chemists and molecular biologists at the Scripps Institute in La Jolla are, on the other hand, completely taken with this virus. They are not setting the tiny things loose on plants, however, but have something completely different in mind: the viruses are to act as... view more... (2002-01-22)
Fetal fat and “red spots” in newborn babies a defense against bacterial attacks
It is common that babies are born with fetal fat and develop red spots on their skin. Pediatricians have always explained this as a passing and normal skin reaction in newborn children. Now Giovanna Marchini at the Karolinska Hospital, Sweden, together with her research team, has discovered that this is a sign of a powerful immune defense system. view more (2003-03-03)
Fill up with biodiesel, please
One day, petroleum and fuels derived from it will be exhausted. Moreover, every time we take to the road in our vehicle, the mark we leave on the natural environment is huge. Nowadays, new alternatives to fossil fuels are being developed. One of these is biodiesel, a fuel produced from vegetable oil. For a month now this biodiesel can be found in... view more...

A baby's smile is a natural high
The baby's smile that gladdens a mother's heart also lights up the reward centers of her brain, said Baylor College of Medicine researchers in a report that appears in the journal Pediatrics today. view more (2008-07-07)
Chemistry sets for grownups
The best thing about chemistry class in school was always the experiments. It stank, it smoked and best of all things exploded. The students were highly delighted when the teacher's own experiments ran out of control. But large-scale chemical accidents are no laughing matter. A reactor containing tons of chemicals can be a real danger. In... view more... (2003-09-18)
Computer predicts reactions between molecules and surfaces, with 'chemical precision'
Good news for heterogeneous catalysis and the hydrogen economy: computers can now be used to make accurate predictions of the reactions of (hydrogen) molecules with surfaces. An international team of researchers, headed by Leiden theoretical chemist Geert-Jan Kroes, published on this subject this week in the journal Science. view more (2009-11-09)
Sick Beans lead to Nanotech
Plant viruses as chemically "programmable" building blocks for nanobiotechnology Farmers get little joy from the cowpea mosaic virus, which attacks legumes. Chemists and molecular biologists at the Scripps Institute in La Jolla are, on the other hand, completely taken with this virus. They are not setting the tiny things loose on plants, however,... view more... (2002-02-05)
Lead exposure plus high blood pressure may impair mental ability
Exposure to lead in early childhood and adolescence may contribute to hypertension-related decline that can impair a person's cognitive abilities, according to a new study presented at the 2005 American Heart Association's High Blood Pressure Research meeting. view more (2005-09-26)
Models begin to unravel how single DNA strands combine
Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix. view more (2009-10-07)
Fine-tuning an anti-cancer drug
Cancer remains a deadly threat despite the best efforts of science. New hopes were raised a few years ago with the discovery that the uncontrolled growth of cancer cells could be thwarted by blocking the action of proteasomes. view more (2009-08-19)
Of Mice and Peanuts: A new mouse model for peanut allergy
Chicago researchers report the development of a new mouse model for food allergy that mimics symptoms generated during a human allergic reaction to peanuts. view more (2009-01-13)
Dancing 'adatoms' help chemists understand how water molecules split
Single oxygen atoms dancing on a metal oxide slab, glowing brighter here and dimmer there, have helped chemists better understand how water splits into oxygen and hydrogen. In the process, the scientists have visualized a chemical reaction that had previously only been talked about. The new work improves our understanding of the chemistry needed... view more...

Micro microwave does pinpoint cooking for miniaturized labs
Researchers at the National Institute of Standards of Technology (NIST) and George Mason University have demonstrated what is probably the world's smallest microwave oven, a tiny mechanism that can heat a pinhead-sized drop of liquid inside a container slightly shorter than an ant and half as wide as a single hair. view more (2007-11-09)
UNC researchers find clue to stopping breast-cancer metastasis
If scientists knew exactly what a breast cancer cell needs to spread, then they could stop the most deadly part of the disease: metastasis. New research from the University of North Carolina at Chapel Hill School of Medicine takes a step in that direction. view more (2008-11-18)
